O.J. Simpson, NFL Superstar, Is Back In Court Fighting for His Freedom After Four+ Years In Prison For 2008 Armed Robbery Charges - VIDEO OF SIMPSON

O.J. Simpson, the former great football player, is back in court, again. On Wednesday, he took the witness stand to make his case for a new trial on armed robbery charges dating to 2008, saying he was relying on the advice of his trusted attorney when he tried to reclaim mementos from his football glory days.

The former NFL superstar also said his trial attorney never told him about possible plea bargains with much less prison time. And he said his attorney assured him he could not be convicted, according to the Washington Post.

After more than four years in prison, Simpson recounted how he and some friends confronted two sports memorabilia dealers in a Las Vegas hotel room in 2007, and how he believed he had the right to take back what he claimed had been stolen from him, including photos and footballs.

"It was my stuff. I followed what I thought was the law," said Simpson. "My lawyer told me I couldn't break into a guy's room. I didn't break into anybody's room. I didn't try to muscle the guys. The guys had my stuff, even though they claimed they didn't steal it," the 65-year-old former NFL star and actor said in his testimony.

Simpson did not testify when he was tried and convicted of armed robbery and kidnapping in 2008. He was sentenced to nine to 33 years in prison.

As reported by the Washington Post, Simpson's new lawyer, Patricia Palm, questioned him about the event, asking that he provide details of a weekend that began with plans for a friend's wedding and ended with him under arrest.

He said he knew the memorabilia dealers, had no fear of them and certainly didn't need guns. "There was no talk of guns at all," he said. Simpson declared he never even saw guns during the confrontation.

During the trial, two former co-defendants who testified for the prosecution said they had guns.

Simpson's chances of being set free hinges on proving his lawyer badly represented him. He mentioned the lawyer, Yale Galanter, from the outset.

"He was my guy," he said of his long friendship and professional relationship with Galanter.

But he blamed Galanter's advice for getting him in trouble. He said Galanter told him he was within his rights to take back his possessions as long as there was no violence or trespassing.

Another Simpson attorney from the 2008 trial has said it was Galanter who pushed on Simpson a decision not to testify.

As reported by the Post, Simpson was asked by Palm if he knew he could have gotten as little as 30 months in prison if he pleaded guilty to robbery, Simpson said no, and that he would have considered it if he had known.

Simpson also said Galanter led him to believe he could not be convicted on the charges.

"If you understood you could be convicted on the state's evidence, would you have testified?" Palm asked.

Simpson said yes.

There is no jury in the hearing and Simpson's fate will be determined by District Judge Linda Marie Bell.
